UNITED STATES PATENT oEEioE Specification of Letters Patent.

Patented Jan. 8, 1907.

Application filed March 14, 1906. Serial No. 306,018.

To all whom, it may concern:

Be it known that I, STUART WARREN CRAMER, a citizen of the UnitedStates,residing at Charlotte, in the county of Mecklenburg and State of NorthCarolinayhai/ejm vented certain new and useful Improvements inHumidifiers vand Air-Moistening Apparatus; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

My invention relates to humidiiiers of the atomizer type for nioisteningthe air in a factory or room, has for its object an apparatus whichshall maintain any preferred amount o1' degree of moisture in the airand diiiuse such moisture throughout the compartment, and at the sametime incidentally therewith cool or warm the air in the room ascircumstances may re uire. It is my purpose to provide means for ceaning the Water-leg of atomizer-heads of this type and to mount them ina new and novel manner, whereby not only is any drip from the headsreturned to the apparatus and not allowed to fall on the mill or factoryoor, and to inclose the operativeparts with a practically tight casing',thereby keeping the same clean and free from lint and otherobjectionable 1iy'1n the atmosphere, which getting into the watersupplywould tend to clog the same.

'.he invention consists in certain improvements in construction, whichwill be fully disclosed in the following specification and claims.

In the accompanying drawings, which form part of this specification,Figure 1 represents a vertical section, partly in elevation, of ah1lruidiiicrembodying my invention; Fig. 2, a plan view of the cover orhood detached;

Fig. 3, a vertical section, partly in elevation,

ol" the humidiiier, taken at a right angle to F ig.

1; and Fig. 4, an enlarged vertical longitudinal section of theatomizer-head.

Reference being had to the drawings and the designating charactersthereon, the numeral 1 indicates a water service-pipe; 2,.awater-reservoir in which a constant level 3 is maintained by a i'loatfeed-tank ot' the usual type, (not shown;) 4, a funnel-shaped drip-panprovided with a rim 5 around the upper end, and the pan is extendeddownward into the reservoir 2 and is supported thereby.

cover, for the sake of convenience, may be made in two parts, separatedeither vlongitudinally or transversely to al'ord ready 'access to theoperating parts Within the cas L 8 8 are orifices in the casing op ositethe atomizer-heads and through which) spray is discharged from theatomizer-heads.`

9 is an air service-pipe connected to an airreceiver or anair-compressor. (Not shown.)

1() indicates an air stop-cock for re the supply of air to theatomiz'er-hea( s;

. 1 1 is a T by which a pair of atomiaer-heads are connected to the mainservice-pipe 9.

- 12 indicates atomizer-heads which upon a Well-known principle delivera iine spray 13 and to the body part of which the air connection ismade.

14 indicates a small orifice through which the air issues.

15 indicates av channel or passage through' the body or head by theoriiice 14 from the T 11.

16 indicates what may be termed the water-leg of the atoinizer-head.

The water-leg is screwed into the body part of the atomizer-head, and atthe u per end of the water-passage is a seat 17 or a movable tip ornozzle 18. The ti has an oscillatory motion and is supporte on a shaft20, carried in bearings 19, and terminates in a ilatt-ened end orthumb-piece v20', by which it may be revolved or rotated in the bearings19. lt will be seen that by swinging the tip or nozzle 1S up by means ofthe shaIt 20 the under side of the tip, which is corneal in shape, willbe directly in the path pf the air-blast discharged throughthe orifice14, by which any accumulation oi" sedimentV or deposit of whatevercharacter' within the tip will be blown out by the blast of air, afterlating` which the air reaches which the tip is returned to its normalposition on its seat 17, freed from obstructions. The tip 18 is held toits seat by a spring 21 to IOC prevent any leakage of air which wouldprevent water from being drawn up through the water-leg by suction.

In addition to the means for cleaning the tip above described needles 21and 22 for theA water and air legs, res `)ect-ively, are provided. Theneedles are rept clear of the` orifices and iny their normal position bbsprings 23 and are pushed into the orifices by .ter-orifice being heads24; lThe needles are made tight inreservoir 2 to the Water-legs 16 ofthe atomi izer-heads. 26 is a wire-gauze strainer in the reservoir 2,and 27 is a s onge or other close material for preventing int or otherforeign matter from getting into the reservoir and at the same timeallows Water to trickle through as it is returned to the reservoir bythe ydrip-pan` 4. 1 n

Havm t'hus fully described my invention, What I c aim is- 1. In' ahumidifier, an atomizer-head having air 'and Water dischar e orifices,said water-orifice 'being provide With a laterallymovable ti and meansfor supplying air and Water-to t e atomizer-head.

l 2. In a humidier, an atomizer-head having air and Water dischargeorifices, a lat-'erally-movable tip for the Water-orifice, meansv forplacing the ti in the path of air-discharge from the air-ori ce, andmeans for supplying air and Water to the 'atomizer-'head '3. In ahumidifier, an atomizer-head having air and Water discharge oriiices,said Warovided with a laterallymovable tip, andp a reciprocatingcleaningneedle, and means for supplying air and Water to theatomizer-head.

4. In a humidifier, an atomizer-head having air and Waterdischargdoriiices, said Water-orifice being rovide movable ti and 0ththe air and Water'o'rifrees rovi ed with a reciprocating cleaningneed e,and means for supplying an` and Water. to the atomizer-head.

5. An atomizer-head provided With air and water discharge orifices, thelatter having a movable tip pivotally secured to the head,

air discharged om t e air-orifice.

6. In a humidier, a pair of atomizer-heads .provided With means forsupplying air and Water thereto, an air-supply pipe to which said headsare attached, a drip-pan, a removable casing resting on and closed vatits lower end by said drip-pan, and provided with a isciarge-apertureopposite each atomizer- -In testimony whereof I alix my signature inpresence of two'witnesses.
